'I his inyention, relates tocnrs or wagons with spec al reference The principal ob ect of the invention is to provide an lmproved, form otirailr'oed car i, .orwagon which isequipped with the de-. vices adapted to weigh the load of the car.

Another ohject'oftlie invention. isito provideo railroad carhavingesupplementsl frame arranged to rotate on the main frame and take position thereon for. Weighing with certain devices attached to the cor,

A third object of the invention is to pro vide, in acer ofthe character described a trunk which may be either held from rotetion eroundits center oorperrnitted to rotate i ii'reely therearound.

A fourth object of the invention is to pro: vide an improved weighing means for a car ofthe character described. I

' With the above and other objects in view 'as will'beconie apparent hereinafter; the device CQilSiSlZS in generel ofa frame supported on'trucks a'second fren'oe Whereon' is built a car bod center of t e first mentioned or main frame an elevating device carried at the centerof the main frame arranged to reise or lower the secondary frame and car body, Weighing devices supported on the mainframe and an "improved form of truck holding device.

The invention further consists incertain noveldetails of arrangement and combina- "tion of parts, hcreinafter'fully described,

illustrated in the accompanying drawings and specifically set forth in the claims.

In the accompanying drawings, like char? actors-of reference indicate like parts in the several views and i the cor body is to be weighed.

perspective view oil, one of In the drawingsappended the nnmernl 10 indicates'one of the center sillsof the lower frame, This frame also provided with the usual .end sills llto which center sills and end sills is "attached a draft gear and coupling as indicated at 12, At 131s shown a body holster oi anypreferred typesyhere in is mounted the body center plate 14 which serves as the point Where the truck pivots. This truck may be of any preferred con struction and .18 preferably provided with leaf springs 16oo 9 i Located centrally of the sills 10 is a casing 1? arranged to form a pocket and Se c'urely bolted to said center sills; ,Mountecl in thiscasing 17 is escrew Wliichis prefer j ably termed the elevating screw 18. This screw is provided zit-its loiver end with a reduced portion having apertures therein within which is fitted a plurality others 19.

in these eperturesor the reduced portion may be made in the form fiffi. capstan head end the bars loosely placed therein when'it I cated thereon is a center bolster 23 wherein is mounted a center plate 24 provided with c a socket at ihe lower end for the reception of the end20 of the sc1'ew18. It will now he observed that by rotating the screw 18 the distance between the mnin'a nd'the s'up- J05 ,plemental framecan be varied as desired.

For the purpose of supporting, the car body and'the supplemental frame when the car is in running position, there is provided on the bolster 1e; ahottomhesring plate 25 f These b'a'rs may be either permanently fitted f having an arcuale ll'ilth 26 mounted thereon. ln like manner. the holster 2;! is provided with a top bearing plan-2T having a grooved arenate track 26 thereon. Thesica tings are provided at each end of the cut and are so arranged a to ll;tll l1lll. the weightguhen' running directly to the trucks.

On each side of thescrew 18,-supportcd between the center sill i is a castina :29 securely bolted to said sill. \Vithin this rastint :29 is formed a cylinder ti provided with a pipe.v threaded aperture at its. lower end. said pipe threaded aperture b in; nunibertal 3.1. A plunger 3:2 is mounted in said cylinder and the cylinder serie to guide said plunger as well as for other purpose to he hereinafter described. This plunger Pr. is provided with a pair ot'arins l t laterally dis:- posed and preferably oppr.i;-itely situated. On each of th arms il is formed a spring reat 3-1 and in alignment therewith on the. bottom of the Casting 29 is formed a similar spring seat. Between each of these spring seats'is provided a weighing s ')rin; 36. These. weighing. springs are carefully adjusted for the weight of the car and load so that a definite deflection of the springs will indicate a definite load in the car. The upper. end of the plunger 32 is provided with a head 37 preferably of a sub-acute, V-sh-ape.

Upon the center sill -'is held an areuate bearing member 38 adapted when the car is in weighing osition to contact with the head 37. Monnte in any desirable position within the car, so that-the conductor or motor-man mayreadily observe same. a weighing gauge 39, preferably of the Bourdon type. These gauges are preferably mounted at the end of the end of the car and they may be separately connected tothe dill'erent cylinders to indicate weight brought upon the springs 36 of the castings 2.). These gauges 39 are connected to the c \'lindcrs'30 by means of'pipcs l provided with joints 41. so that when the ear is revolved the tfHlllPtflllJll may not; be broken.

In the operation of the device thus far described, let it be assumed that the ear is in the position indicated in Figure l and that it is loaded. If it he desired to acertain the weight of the loaded car. the H'POIltlHI') frame is raised by actuating the screw 154 in the proper direction. and the btaly rotated on its central axis. which bring the body into the position shown in Figure 2. The motion of thescrew l8 is then reversed and the car allowed to come down upon the plunger head 37. The pres-are of the fluid contained in the cylinder 30 i then transmitted to the gauges 39 and the weight or the car recorded thereon. The operation i then reversed and the car brought back to its running positio as indicated in Figure 1 In order to prm lde means for securely locklag the car in its running position. suitable rolling one.

bolts, preferably four in number, are held at, 42 in castings 43. 'lhese'castings are preferably located at each end of the bolsters Z2 and upon the bolsters 13 are provided similar castingrs 44 adapted to receive the ends 7 pair of eye-bolts l5 and upon the bottom of the frame are carried chains 46 having books I at their ends to engage. the eye-bolts 45. By

this means-the trucks. are prevented from rotating with reference to the lbwer franie F1? while. at the same'time. the hooks can be disengaged from the eye-bolts and the trucks permitted to rotate to any desired 4 sition.

. In order to provide means for hol ing the wheels from rotation and preventing the wear due to the friction of same on therails or road when held by the brakes,' there are carried by the lower frame chains 47 which are equipped at their outer ends with drags or clogs 48 of suitable form to .receive the periphery or rim of the wheels and to' ernnt the wheels to rest thereon instead 0 on the ground. When t is desired to prevent the wheelsfrom 'rotating, these drags on osit'ioned in front' of said clogs are simply wheels and thew reels are allowed to run up thereon. Thedra gs or clogs will then interpose between the road and the motion of the car will bea sliding motion rather than it There has thus beenprovidcda newv and efficient-device of the character described and I for the purposes-specified. It is not desired to eonfine'the invention to the exact form.
